广东莲花山白盆珠自然保护区吊皮锥群落特征

摘要

采用样方调查法，对莲花山白盆珠自然保护区吊皮锥（Castanopsis kawakamii）群落的物种组成、属的地理成分、群落结构及种群结构特征进行研究。结果表明，在3个400 m2的主样方中，共记录了维管植物71种，隶属于32科45属，以茜草科（Rubiaceae）、樟科（Lauraceae）、壳斗科（Fagaceae）和山茶科（Theaceae）为优势科，以大节竹（Indosasa crassilfora）、吊皮锥和革叶铁榄（Sinosideroxylon wightianum）为优势种，吊皮锥种群均为中树或大树，林下缺乏幼苗小苗；在其他12个副样方中均未见到吊皮锥个体，反映了吊皮锥种群为衰退型。基于研究结果提出了吊皮锥资源保护及可持续发展的建议。%The characteristics of species composition, generic elements, community structure and population structure withCastanopsis kawakamiiwere studied by plot method in Lianhuashan-Baipenzhu Nature Reserve. There were recorded 71 vascular plant species belonging to 32 families and 45 genera in three plots with a total area of 1 200 m2. The dominant families are Rubiaceae, Lauraceae, Fagaceae and Theaceae. The dominant species areIndosasa crassilfora,C. kawakamiiandSinosideroxylon wightianum. The population ofC. kawakamii was made up of large-sized trees. No seedlings and saplings were found. No individuals ofC. kawakamiiwere found in surrounding vice-plots. Based on the results of the population ofC. kawakamiiwas degraded, this paper presrented the suggestions of reserous protection and sustainable development ofC. kawakamii.
